Abstract

PURPOSE:To set dial data and the combination of a prescribed operation to be peculiar to every mobile station by storing the dial data in the mobile station, and originating a call by transmitting the dial data from the mobile station to a fixed station according to the prescribed operation. CONSTITUTION:A RAM 15 capable of being used as a work area and an EEPROM 11 for registering telephone number data are connected to the control part 9 of the mobile station 2, and an operating part 10 almost the same as the operating part of the fixed station 1 is connected. Thus, since the mobile station 2 is provided with a memory to register a telephone number, and the telephone number data is registered in this memory correspondingly to a one- touch key, the registering processing of the telephone number can be performed independently for every mobile station even in the case that plural mobile stations are radio-connected to the fixed station. Since the dial data is transmitted from the mobile station to the fixed station directly mot by a control signal corresponding to an abreviated dial, a call originating processing can be performed according to the transmitted dial data at the fixed station.

Description

Detailed Description of the Invention Field of Application of "# Business" The present invention comprises a communication device, particularly a fixed station connected to a terminal of a predetermined communication line, and a mobile station wirelessly connected to the fixed station. The present invention relates to a communication device that performs communication using a predetermined method between a mobile station and a line.

[Prior Art] Cordless telephones have been known as communication devices as described above, which are not limited by the length of a cable and are capable of making calls via a mobile station while freely moving. Some cordless telephone systems are known to operate by combining one fixed station (base unit) and one mobile station (slave unit), but recently, multiple mobile stations are connected wirelessly to one fixed station. Connection methods have also been proposed.

[Problems to be Solved by the Invention] On the other hand, in the case of a normal wired telephone, a memory in which telephone numbers are registered is provided, and a desired one of the registered telephone numbers can be dialed by speed dialing or one-touch key operation. A method is known in which a call is made to the other station by selecting a destination. Although it is thought that such a calling system is possible for cordless telephones as well, the telephone number storage system for conventional cordless telephones is such that a memory for storing telephone numbers is provided on the fixed station side.

In such a conventional configuration, if a system consisting of one fixed station and one mobile station does not cause any problems, or one
In systems that allow multiple mobile stations to be connected to one fixed station, in systems in which the telephone number is stored in the fixed station, dial data can be registered in association with an abbreviated dial operation that can be used commonly by all mobile stations or a one-touch key. Must.

In that case, for example, operators of mobile stations that may be connected to a rotary fixed station would have to get together and decide in advance the combination of phone numbers to be memorized and speed dials or one-touch keys. Furthermore, it is almost impossible to implement a system in which each mobile station can perform registration operations freely.

When storing telephone numbers in a fixed station, the above problem can be avoided by setting up a speed dial memory area for each mobile station that may be connected to the fixed station. It is necessary to select the divided memory area as described above according to the station identification result, which complicates the fixed station control system. Since it has to be small, it becomes difficult to make effective use of memory, and problems arise such as the hardware becomes too weak.

The object of the present invention is to solve the above problems.

[Means for Solving the Problems] In order to solve the above problems, the present invention comprises a fixed station connected to a terminal of a predetermined communication line, and a mobile station wirelessly connected to the fixed station, A communication device that performs communication using a predetermined method between a mobile station and a communication line, comprising a storage means for registering dial data for calling a partner station in the mobile station, and inputting the stored dial data to a predetermined operation input. If dial data registered in the storage means is designated by the designation means, the designated dial data is transmitted from the mobile station to the fixed station in a predetermined signal system, and A configuration is adopted in which the dial data is sent from the terminal to the communication line.

[Operation] According to the above configuration, the dial data is stored in the mobile station instead of the fixed station, and based on a predetermined operation, the dial data can be transmitted from the mobile station to the fixed station to make a call. .

The mobile station 2 is also provided with a control section 9 consisting of a microprocessor or the like. A control program for the control unit 9 is stored in the ROM 9a. Also connected to the control unit 9 are a RAM 1.5 used as a work area, etc., and an EEPROM I 1 for registering telephone number data. Further, an operation section 10 substantially similar to the operation section of the fixed station 1 is connected to the control section 9 .

FIG. 2 shows an example of the configuration of the keyboard of the operating section 7.10 of the mobile station 2 (or fixed station 1) shown in FIG. In FIG. 2, 2:f'; 3104 is a numeric keypad for inputting the Atayardek, which is composed of numeric keys "0" to "9" and input keys such as "tree" and "#". Additionally, the 10 keys arranged on the right side of the numeric keypad 104 are one-touch keys 1 and 03, one of which is EEPROMI.
It is associated with the 'telephone number stored in 1.

Also, at the bottom of the numeric keypad 104 is a read/write key 1.
01 and a clear key 102 are provided. A read/write key 101 is used to control registration and reading of telephone numbers to and from EEPROM 1,1. Clear key 102 is used to clear speed dial or re-dial data. Note that the key designated by reference numeral 105 is a dial key for making a call again using the telephone number used for the previous call.

Next, the operation of the above configuration will be explained with reference to the flowchart of FIG. FIG. 3 shows a control procedure performed by the control unit 9 of the mobile station 2. This hand j1 "1" is stored in the ROM 9a of the mobile station 2.
In the flow of C), it is assumed that control continues over the same numbered positions.

FIG. 3(A) shows the main routine on the mobile station 2 side. First, in steps S4 and S5, operations of the read/write key 101 and the one-touch key 103 are detected, respectively. Read/Write key], 01, one-touch key 10
If the read/write key 101 is pressed continuously, the process goes to step S6, and if the press of the read/write key 01 is denied, the process goes to step S21 of FIG. If the press of 103 is denied, the third
The process advances to step S31 in Figure (C).

If the button is pressed three times in a row, the phone number registration process from step S6 onwards is performed. First, in step S6, the address assigned to the pressed one-touch key is stored in the internal register of the control unit 9, and then in step S7.
04 is operated.

If the numeric keypad 104 is operated, the process proceeds to step S8; if there is no operation, the process proceeds to step S5.

In step S8, data corresponding to the pressed numeric keypad is buffered in the RAM 15. Ste.

In step S9, pressing f of the read/write key 101 is detected, and if this key is pressed, the process advances to step 310; if not, the process advances to step SL].

In normal registration processing, the numeric keypad is pressed multiple times, so the process proceeds to step Sll, where pressing of the clear key 102 is detected. If the clear key is pressed, the process proceeds to step S12; if not, the process proceeds to step S7.

When the numeric keypad 104 is pressed repeatedly, the data corresponding to that key is successively buffered in the RAM in a loop of steps 87 to S9 and S11, and the data corresponding to the key is repeatedly pressed in the RAM.
When 1 is pressed, the process proceeds from step S9 to 310, and in step S6 the EEPROMI indicated by the stacked register is
The data expanded to the RAM 15 is allocated to address 1. If the clear key 102 is pressed during input, the process advances from step Sll to S12, where the address data in the register and the data in the RAM 15 are cleared.

On the other hand, if the manual input of the numeric keypad is denied in step S7, the process proceeds to step S15, where pressing of the read/write key 101 is detected. When the Read/Rye I key 101 is pressed, the process proceeds to step S10, and (No) j! Step S
], the process advances to step 6 and detects that the clear key 102 has been pressed. When the clear key 107 is pressed, the address in the register is cleared in step S17. If step 316 is negative, the process returns to step S7. Step 5IO1S
12. When S17 ends, the process moves to another control routine.

As described above, by pressing a desired one of the read/write key 101 and the one-touch key 103, and then inputting a desired telephone number using the numeric keypad 104, and pressing the read/write key 101 again, the telephone number The EEF is associated with the one-touch key 103 that was pressed first.
It can be stored in ROMI 1. Input data can be erased or changed using the clear key 102.

In addition, once it corresponds to the one-touch key 103, the EEP
Data stored in ROMI 1 can also be deleted. In that case, the procedure shown in FIG. 3(C) is used. That is, if the press of the one-touch key 103 is denied in FIG. 3(A), the process proceeds to step S31 of FIG. 3(C), and the press of the clear key 102 is detected. If it is affirmative that the clear key has been pressed, the process proceeds to step 332, but if it is denied, the process returns to step S5. In step S32, pressing of the one-touch key 103 is detected. If the one-touch key 103 is pressed, the process advances to step S33; if not, the process advances to step S34.

In step S33, the telephone number data in the address of the EEPROM II corresponding to the pressed one-touch key 103 is deleted.In step S34, pressing of the read/write key 101 is detected, and if it is not pressed, step S3

The telephone number data is read from the address of OMI 1 and output to the fixed station.

On the other hand, if the ten key is pressed in step S21, data corresponding to the pressed key is transmitted to the fixed station 1 in step S24. In this case, the data is transmitted to the wireless connection section 12.
The data transmitted via the transmitting section of the fixed station 1 and received by the fixed station 1 via the wireless connection section 8 is given to the dial signal sending section 5 by the control section 6 and sent to the communication line 3. In step S25, the hook state of the handset of the communication unit 13 is detected. If the hook is on, the process proceeds to other controls, but if the hook is off, the manual telephone number input in steps S21 and S24 is repeated.

The dial data transmitted to the fixed station 1 in steps S23 and S24 are sequentially input to the dial signal transmitting section 5 under the control of the control section 6, and a corresponding dial signal is transmitted to the communication line 3.

This allows you to make a call to the other party.

Note that actual call control is performed as follows.

First, when the handset of the communication unit 13 of the mobile station 2 is in the on-foot state, the power to the transmitting unit of the wireless connection unit 12, the EEPROM 11, etc. is cut off in order to prevent consumption of the power supply circuit consisting of a battery or the like. When hook-off is performed, power is supplied to these circuits and a hook-off signal is transmitted via the wireless connection section 12. The fixed station 1 that receives this sends and receives predetermined information via the control channel, and sets up a communication channel between the fixed station 1 and the mobile station 2. Thereafter, the control unit 6 of the fixed station 1 controls the line interface circuit 4
Make a line connection through the line and close the line DC loop.

Thereafter, the control unit 6 of the fixed station 1 notifies the mobile station of information indicating that the hook-off process has been completed via the control channel, and then sends information to the mobile station 2 via the communication channel.
Send the dial tone of the line to. When the mobile station operator confirms this status, he presses the numeric keypad 104 or the one-touch key 1.
03 to enter the phone number. This input operation is the third
Detected by the procedure shown in the figure, steps S23 to S2
4, the dial data is transmitted to the fixed station l, and a dial signal corresponding to the dial data is transmitted to the communication line 3.

According to the above configuration, the mobile station is provided with a memory for registering telephone numbers, and telephone number data is registered in this memory in correspondence with one-touch keys, so multiple mobile stations can be connected to a fixed station. Even when connected wirelessly, each mobile station can perform its own telephone number registration process.

Since dial data is directly transmitted from the mobile station to the fixed station rather than a control signal corresponding to one-touch keys or speed dialing, the fixed station only needs to perform call processing based on the transmitted dial data. Furthermore, according to the embodiment described in (-) above, since the telephone number data is stored in the EEPROM, the registered telephone number can be retained without requiring a backup power supply or the like.

However, it goes without saying that a normal RAM or the like may be used for registering the telephone number.

Further, although control using one-touch keys has been described in -1- below, it goes without saying that the same effect can be obtained even if a telephone number is registered in response to a predetermined speed dial operation using a numeric keypad.

Moreover, although the configuration of a cordless telephone has been exemplified above, it goes without saying that a similar configuration can be implemented as long as it is a device that communicates between a mobile station and a communication line via wireless communication with a fixed station.

[Effects of the Invention] As is clear from the above, the present invention comprises a fixed station connected to a terminal of a predetermined communication line and a mobile station wirelessly connected to the fixed station, and the mobile station and the communication line In a communication device that performs communication in a predetermined manner between the mobile station and the mobile station, a storage means for registering dial data for calling a partner station in the mobile station, and a means for specifying the stored dial data based on a predetermined operation input. and when the dial data registered in the above-mentioned t(E means) is specified by this specifying means, the specified dial data is transmitted from the mobile station to the fixed station in a predetermined signal system, and the specified dial data is transmitted from the fixed station to the fixed station. Since we have adopted a configuration that sends the dial data to the communication line,
Dial data is stored in the mobile station instead of in the fixed station, and the dial data is transmitted from the mobile station to the fixed station based on a predetermined operation to make a call. Therefore, even when a mobile station is connected to a plurality of fixed stations, there is an excellent effect that a unique combination of dial data and predetermined operations can be set for each mobile station.
